FAIRFAX COUNTY, Va. (WJLA) - A man accused of setting off explosive devices at his estranged wife’s parents’ home in Bethesda early Sunday has been arrested in Fairfax County.

Montgomery County Police say the homeowner recognized his son-in-law, Marc Cassell, 36, who was banging on the front door and was attempting to force his way into the house.

The father-in-law saw sparks and smoke coming into his home in the 11400 block of Marcliff Road in Bethesda. A second explosive device was set off near the garage and caused significant damage, police say.

Cassell and his wife are involved in an ongoing divorce and custody dispute, police say.

When Fairfax police were alerted that Cassell had fled to Virginia later in the morning, they arrested him and are holding pending extradition to Montgomery County.
